Matrix-type display panel and driving method therefor
First Claim
1. A driving method for a matrix-type display panel of the type comprising a display panel having a plurality of scanning lines, a plurality of data lines and a plurality of picture elements disposed at each intersection of the scanning lines and data lines, and analog switching elements for sampling-and-holding information signals which are applied to the data lines in synchronism with scanning signals applied to the scanning lines, wherein said analog switching elements are divided into first and second groups of analog switching elements which are connected to a first shift register and a second shift register respectively, said driving method comprising the step of:
- successively applying switching pulses to said analog switching elements so that a pair of switching pulses successively applied to an analog switching element in said first group and an analog switching element in said second group, respectively, are sequenced so that said pair of switching pulses at least partially overlap each other in time.

Abstract
A matrix-type display panel comprises a display panel having a plurality of scanning lines, a plurality of data lines and a plurality of picture elements disposed at each intersection of the scanning lines and data lines, and analog switching elements for sampling-and-holding information signals which are applied to the data lines in synchronism with scanning signals applied to the scanning lines. The matrix-type display panel is driven by a driving method comprising: applying such switching pulses to the analog switching elements that time-serial pulses among them and shifted in phase from each other and overlap each other in a same duration.

10. A matrix-type display panel, comprising:
-
a display panel having a plurality of scanning lines, a plurality of data lines divided into a first group and a second group, and a plurality of picture elements disposed at each intersection of the scanning lines and the data lines; a first group of analog switching elements each connected to one of the first group of data lines, and a second group of analog switching elements each connected to one of the second group of data lines; a first group of sample-and-hold capacitors each connected to one of the first group of analog switching elements, and a second group of sample-and-hold capacitors each connected to one of the second group of analog switching elements; a first shift register connected to and supplying switching pulses to said first group of analog switching elements, and a second shift register connected to and supplying switching pulses to said second group of analog switching elements; and means for providing a pair of successively applied switching pulses from said first and second shift registers, respectively, such that said pair of successively applied switching pulses at least partially overlap in time. - View Dependent Claims (11, 12, 13, 14)
